Police have detained Neha Bora, national president of the All India Students’ Association (AISA).
She was reportedly inside a police bus as protesters gathered around it.
The incident took place amid protests against Chief Election Commissioner Gyanesh Kumar and the Special Intensive Revision (SIR) of electoral rolls.
In a post on social media platform X, AISA said it had planned to hold a demonstration at Jantar Mantar in Delhi but shifted the venue to Delhi Haat because of heightened security arrangements. Police maintained tight security across New Delhi. Surveillance and security measures continued even after the protest venue was changed.
